Using read.csv() is the reload option. R has no automatic interface to external files. > 2) I am creating a histogram. I need on x axis 24 hours to be displayed > separately as 0,1,2, and thereon.

Add a custom axis. Add custom labels. # using fake data aaa <- data.frame(Hours = sample(1:24, 10000, replace=TRUE)) aaa.hist <- hist(aaa$Hours, main="Hourly Weight", xlab = "Time", breaks = seq(0, 24), col = "yellow", ylim = c(0,9000), cex.axis=0.6, xaxt="n") axis(1, (0:23)+.5, 1:24, cex.axis=.6) text((0:23)+.5, aaa.hist$counts-150, aaa.hist$counts, cex=.6) Sarah -- Sarah Goslee http://www.functionaldiversity.org ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
